A Comparison of Mechanisms for Improving TCP Performance Over Wireless Links
Overview Reliable transport protocols such as TCP are tuned to perform well in traditional networks where packet losses occur mostly because of congestion. However, networks with wireless and other lossy links also suffer from significant losses due to bit errors and handoffs. TCP responds to all losses by invoking congestion control and avoidance algorithms, resulting in degraded end-to-end performance in wireless and lossy systems. This paper compares several schemes designed to improve the performance of TCP in such networks. These schemes are classified into three broad categories: end-to-end protocols, where loss recovery is performed by the sender; link-layer protocols, that provide local reliability; and split-connection protocols that break the end-to-end connection into two parts at the base station.
